Specification of Letters Patent.

Patented Mar. 26, 1912.

Application filed June 21, 1910. Serial No. 568,147.

may be used in connection with beds of the ordinary type and which willenable the nurse to readily raise a stretcher, on which the patientrests, to a position above the mattress of the ordinary bed.

Another obj cct of the invention is to provide the stretcher with ahinged back member and means by,which it may be raised, relatively tothe stretcher, so that the patient may besupported while sitting up inbed.

Still another object of the invention is to provide a detachableextension apparatus, to which adhesive strips are secured, which may beattached to a limb of the patient in cases of fracture to reduce thedanger of the limb becoming shortened.

Still other objects of the invention will appear in the followingcomplete description.

In this specification I will describe the preferred form of myinvention, it being understood that the scope of the invention isdefined in the appended claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which Figure 1 is aperspective view of my apparatus in use; Fig. 2 is a side elevation ofthe same; Fig. 3 is an end view at the head of the bed; Fig. 4: is atransverse sectional view looking toward the foot of the bed, and Fig. 5is a fragmentary view, showing one set of the bars at the ends of thestretcher for keeping the reinforcing bars spaced from each other.

By referring to the drawings, it will be seen that four standards 5 areprovided, two of these standards 5 being disposed at the foot of the bedand two at the head. These standards 5 are connected at their bottom bybase members 6, and at their upper terminals by transverse frame members7, respectively. Rollers 8 are journaled in the trans- .verse framemembers 7, belts 9 being secured to the rollers 8 at one set of theterminals, the other set of the terminals being secured around eyes orloops 10, which are normally engaged by hooks 11 secured to the sidemembers 12 of a stretcher 13. These side members 12 of the stretcher 13are connected at each end by a pair of transverse members 14. At eachend one of the transverse members 1% is secured to one of the sidemembers 12, the transverse members being secured together by clamps 149,the transverse members and the clamps serving as expanders. The canvas15 of the stretcher 13 is reinforced at its sides by bars 15* and islaced to the transverse members 14. Straps 12 are secured to thereinforcing bars 15 and are disposed over the side member 12. Thiscanvas 15 has an opening 16 therein. To the side members 12 of thestretcher 13 are hinged side members 17 of a back 18, arm-rests 19 beinghinged to the side members 17, two curved arms 20 being hinged to thebottom of the arm-rests 19, the arms 20 being disposed through openings21 in' the side members 17 and being provided with teeth for engagingthe sides of these openings, by which means the arm-rests may beadjusted and may be supported to meet all needs. The side members 12 ofthe stretcher 13 have openings 22 through which the curved arms 20 aredisposed when the back 18 is lowered.

Connecting the transverse frame members 7 are three rods 23, one ofthese rods 23 being provided with a yoke 24 in which are j ournaledrollers 25, cords 26 bemg provided, these cords having one set ofterminals secured to the back 18, the cords being disposed around therollers 25, the other set of terminals of the cords being secured to adrum 27. The drum 27 is secured to a shaft 28, the shaft 28 beingjournaled in lugs 29 which are secured to the transverse frame members 7at the head of the bed. A crank 30 is secured to the shaft 28, by whichit may be rotated. A pawl 31 is-pivoted to the transverse frame member 7at the head of the bed, this pawl engaging a ratchet wheel 32 secured tothe shaft 28. The rollers 8 extend through the transverse frame member 7at the head of the bed. A shaft 33 is journaled in bearings 34, securedto the standards 5 at the head of the bed,

worm gears 35 being provided which connect the rollers 8 with the shaft33, a crank 36 being secured to the shaft 33, by which means the shaft33 may be rotated and the belts 9 may be wound or unwound on the rollers8, as may be desired. By referring to Fig. 3 of the drawings, it will beseen that one of the worm gears has a righthand thread and the other aleft-hand thread, so that the belts may be wound or unwoundsimultaneously on the rollers 8 by the rotation of the shaft 33.

The extension apparatus at the foot of the bed consists of a clampmember 37 having an opening 38 in which the standard 39 is disposed,this clamp 37 having depending flanges 40 at its terminals, there beinga threaded orifice in one of these depending flanges 40 in which a screw41 meshes. The other depending flange 40 is disposed against the innerside of the transverse member 14 of the stretcher 13, situated at thefoot of the bed. Itwill therefore be seen that when the screw 41 isturned home, it will engage the standard 39 and will press it againstthe outer side of the said transverse member 14 of the stretcher 13, bywhich means the standard will be held in position relatively to thestretcher. This standard 39 may be bent outwardly and upwardly, asindicated in the drawings. The upper terminal of the standard 39 isbifurcated and a pulley 42 is journaled in this bifurcated portion. Acord 43 is disposed over the pulley 42, the inner terminal of the cord43 being secured to a block 44, the other terminal being secured to abar 45, to which weights 46 are attached. The block 44 is cut into twomembers, which are secured together by screws 47, an adhesive strip 48being disposed between the members of the block 44, after which themembers are secured by the said screws 47. A support for the foot of themattress 49 has transverse members 50, which are secured to curved legsections 51, the leg sections 51 being provided with guideways 52 inwhich the curved leg sections 53 are disposed, screws 54 being providedwhich mesh in threaded orifices in the leg sections 51 in closeproximity to the guideways 52, the screws 54 engaging the leg sections53 to hold them relatively to the leg sections 51. Bearings 58 aresecured to the side members 12 of the stretcher 13 at the foot of thebed, rollers 59 being journaled in these bearings, the guide wheels engaging the standards 5 at the foot of the bed to guide the stretcher 13as it is raised and as it is lowered.

In using my invention, the head 55 of the side members 56 of the bed isleft in position, but the foot of the bed is removed, the side members56 of the bed of the ordinary type resting on the transverse members 50of the support. The mattress 49 is support ed on the side members 56 inthe usual manner. The side members 56 and the mattress 49 are supportedby the head 55 of the bed and the transverse members 50 of the support.The standards 5, with the base mem ber 6 and the transverse frame member7, are disposed at the head and foot of the bed, as shown in Fig. 1 ofthe drawings, the standards 5 at the foot of the bed being disposed at agreater distance from each other than are the standards 5 at the head ofthe bed, the standards 5 at the foot of the bed also being disposed awayfrom each other a distance greater than the width of a single bed, sothat the standards 5 at the foot of the bed may be disposed one at theouter side of each of the side members 56, this construction beingprovided to facilitate the movement of the standards into position.

Then the standards are in position, it will be understood that thestretcher 13 is disposed over the mattress 49. It will also beunderstood that the stretcher 13 may be raised or lowered by means ofthe crank 36. The back 18 may be raised, or may be lowered relatively tothe stretcher 13, by means of the crank 30, it being possible to adjustreadily the back 18 relatively to the stretcher 1.3, no matter at whatheight the stretcher is raised above the mattress 49. It will also beclearly understood that the clamp 37 may be disposed with one of itsflanges against the inner side of the transverse member 14 at the footof the stretcher, so that by turning the screw 41, the standard 39 willbe held in position relatively to the stretcher, permitting thearrangement of the block 47, the cord 43 and the weight 46. The armrests19 may be readily raised and adjusted relatively to the back 18 by meansof the curved arms 20, having the teeth which engage the orifices in theside members 17 in the back.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
